Why Email Marketing Still Works in 2025

In a world of TikToks, DMs, and AI-driven ads, email marketing might feel... old. But don’t be fooled.

According to Statista, over 392 billion emails are sent every day in 2025 — and email continues to deliver the highest ROI of any marketing channel.

When powered by HubSpot, your email campaigns become smarter, faster, and more profitable.

Let’s look at the best practices for using HubSpot email marketing in 2025.

1. Use Smart Lists for Laser-Focused Segmentation

Gone are the days of blasting one email to your entire list.

With HubSpot Smart Lists, you can segment your contacts based on:

• Recent activity (last purchase, last email opened)

• Demographics (location, job title, language)

• Lifecycle stage (lead, MQL, customer)

• Product interest or behavior

🎯 Pro Tip: Create a “Hot Leads” list of contacts who visited pricing pages 3+ times in the last 7 days.

2. Leverage HubSpot’s Personalization Tokens

Make every email feel 1-on-1 — even when sending to thousands.

Use personalization tokens to insert:

• First name

• Company name

• Last product viewed

• Custom properties from your CRM

💡 Bonus: Try using smart content blocks to show different offers to different audience segments in the same email.

Example:

• Returning visitors see a discount

• New subscribers get a welcome guide

3. Build Automated Workflows (Set It and Scale It)

Email automation isn’t just for welcome emails anymore.

Use HubSpot Workflows to:

• Onboard new users

• Send abandoned cart follow-ups

• Nurture leads after a webinar

• Upsell based on past purchases

• Win back inactive customers

📈 Example:
If a user downloads your ebook and doesn’t open your next 2 emails — trigger a special reminder email with a different subject line and a new offer.

4. Optimize for Mobile (Non-Negotiable in 2025)

Over 75% of emails are opened on mobile devices in 2025. HubSpot’s drag-and-drop editor makes it easy to build responsive emails — but don’t forget to:

✅ Use large buttons
✅ Keep subject lines under 45 characters
✅ Avoid large image files
✅ Test your email in both dark and light mode

Use Litmus or Email on Acid for extra email previews.

5. A/B Test Everything

HubSpot lets you A/B test:

• Subject lines

• Send times

• CTA button styles

• Content layout

🧪 Always test one variable at a time.
Track results and let HubSpot automatically send the better-performing version.

6. Improve Email Deliverability with HubSpot Tools

Great emails don’t matter if they land in spam.

Tips to boost deliverability:

• Authenticate your domain (SPF, DKIM, DMARC)

• Use a real sender name and reply-to email

• Avoid spammy words like “Free $$$” or “Guaranteed”

• Keep your bounce rate low (under 2%)

• Clean inactive subscribers every 3–6 months

Check Google Postmaster Tools to monitor reputation, and use HubSpot’s built-in email health tools.

7. Respect Privacy and Compliance

2025 brings stricter privacy laws in the U.S. (like California's CPRA), and HubSpot makes it easier to stay compliant.

Be sure to:

• Always include an unsubscribe link

• Ask for double opt-in when possible

• Allow contact property deletion if requested

• Use GDPR/CCPA modules in HubSpot forms

🔒 Better compliance = better trust = better performance.

8. Track ROI and Revenue per Email

With HubSpot’s reporting dashboard, you can track:

• Open rate

• Click-through rate

• Revenue per email

• Attribution by channel

• Contact lifecycle stage progress

Use Revenue Attribution Reports to connect campaigns directly to deals and sales.
